RAILWAY-SWITCH.

Specification of Letters Patent.

Patented May 24, 1910.

Application filed November 13, 1908. Serial No. 462,484.

Hungary, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Railway- Switches, of which the following is a specification, reference being had therein to the accompanying drawin This invention relates to railway switches, and the primary object of our invention is the provision of novel means for automatically throwing a switch from the cab of a locomotive, and thereby dispensing with switchmen.

A further object of our invention is the provision of novel means in connection with a double-throw switch for holding the switch in a thrown position, while the train is passing over the same.

With the above and other objects in view, which will more readily appear as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently described, and then claimed.

In the drawings, Figure 1 is a plan of a switch constructed in accordance with our invention, Fig. 2 is a side elevation of the same illustrating a locomotive actuating a switch, Fig. 3 is an enlarged side elevation of the switch throwing device, Fig. 4 is an end view of the same, Fig. 5 is a longitudinal sectional view of the switch throwing device, Fig. 6 is a cross sectional view of the same, and Fig. 7 is a plan of the same.

In the accompanying drawings, 1, 2 and 3 designate ties or sleepers adapted to sup port the rails for forming part of a switch. The rails 4 and 5 constitute a main track, while the rails 6 constitute a sliding track. The passage of a train from the rails 4 to the rails 6 is controlled by movable switch tongues 7, these tongues being secured to a bar 8 slidably mounted under the outer rails 5 and 6 and upon one of the ties 2.

At one side of the main rails 4, we arrange a suitable foundation 9 for a casing 10 having a central transverse vertical partition 11. The upper end of the partition 11 is bifurcated, as at 12 for a rock arm 13 which is fulcrumed in the bifurcation of said partition by a pin 14. The movement of this rock arm 13 is limited by transverse pins 15 arranged in the casing 10. Journaled in the lower part of the casing 10 are sheaves 16 and 17, and arranged upon the ties 3 are guides 18 for connecting rods 19 and 20. The rod 19 is connected by a chain 21 to one end of the rock arm 13, as at 22, said chain passing under the sheave 16. The rod 20 is connected by a chain 23 to the opposite end of the rock arm 13, as at 24, said chain 23 extending through an opening 25 in the partition 11 and under the sheave 17.

The forward ends of the rods 19 and 20 ing around the horizontal sheaves 31 revo- V lubly mounted upon the opposite ends of the ties 2.

The rock arm 13 is provided with lateral extensions 32 supporting a hanger 33 and movably mounted upon the hanger 33 is a grooved roller 34 from which is suspended a weight 35. adapted to travel upon the rails 4 is provided with an actuating rod 38 adapted to extend from the cab and engage the upper surfaces of a rock arm 13. The actuating rod 38 is slidably mounted in the cab 36 and is moved in and out of the cab and in and out of operative relation with the arm 13 through the medium of a throttle 39 loosely connected to a yoke 40, carried by the actuating rod 38.

Operation: As shown in Figs. 1 and 2 of the drawings, the actuating rod 38 has moved the switch tongues 7 to permit the locomotive 37 passing on the rails 5. This has been accomplished by the actuating rod striking the rock arm 13, lowering the rear end thereof, and through the medium of chains 21 and 23, connecting rods 19 and 20, chains 26 and 27, bar 8 and rod 28, and chain 30, the bar 8 has been shifted to move the switch tongues 7 in the position shown in Fig. 1. WVith the rock arm 13 in the position shown in Fig. 2, a locomotive could pass onto the side rails 6 by lowering the rear end of the rock arm 13, and thereby shifting the switch tongues 7 toward the rail 5. The hanger 33 and the weight 35 movably mounted thereon, is employed for The cab 36 of a locomotive 37 firmly holding the switch tongue 7 in the position to which they are adjusted.

It is optional with the engineer of the locomotive 37 as to whether the locomotive is to continue on the main rails or enter the siding, as the actuating rod 38 can be easily shifted, if the switch tongues 7 are not properly set or withdrawn out of the path of the rock arm 13 if the tongues are properly set, it being noted however, that for actuating the arm 13 to open the switch to the side rails as above set forth, the engine being positioned as shown in Fig. 2 would be required to slightly back up, but as this would only be necessary in taking the siding and when coming from the one direction indicated, no disadvantage would result from this necessary backing operation.

Our switch has been designed for tracks upon which trains travel in one direction, as east bound tracks, it being of course understood that the switches reverse for a west bound track.

lVhile in the drawings forming a part of this application there is illustrated the preferred embodiments of our invention, we would have it understood that the details of construction can be varied or changed as to the shape, proportion and manner of assemblage, without departing from the spirit of the invention.

Having now described our invention,what we claim as new, is

1. In a railway switch, the combination with a main track, a siding track, switch tongues controlling the movement of rolling stock from said main track to said siding track, and an actuating rod movably carried by the cab of a locomotive adapted to travel upon said tracks, of a bar connecting with said switch tongues, a casing located adja cent to said main track, a rock arm fulcrumed in said casing and having connections with said bar for shifting said bar, said rock arm being adapted to be engaged by said actuating rod for shifting said bar' and the switch tongues connected thereto, a hanger carried by said arm, a weight movably mounted upon said hanger for firmly holding the switch tongues in a shifted position, and means arranged in said casing for limiting the movement of said rock arm.

2. In a railway switch, the combination with a main track, a siding track, switch tongues controlling the movement of rolling stock from said; main track to said siding track, and an actuating rod movably carried by the cab of a locomotive adapted to travel up on said tracks, of a bar connecting with said switch tongues, a casing located adjacent to said main track, a rock arm fulcrumed in said casing and having connections with said bar for shifting said bar, said rock arm being adapted to be engaged by said actuating rod for shifting said bar and the switch tongues connected thereto, a hanger carried by said arm, and a weight movably mounted upon said hanger for firmly holding the switch tongues in a shifted position.

In testimony whereof we aflix our signatures in the presence of two witnesses.
